Please help if u can! :))))

Maurinko [17]

Answer: 0.8

Step-by-step explanation:

The formula to find area of a parallelogram is A = bh. This means that area = base x height. You can manipulate this formula to what height equals instead of the area. To do that, you can divide b on both sides. This would make the equation h = A/b.

Now that you know how to find what height equals, first find the base of the parallelogram. To find b, multiply 6 x 5. 6 x 5 = 30. This means that your base is 30.

Take the information given to you in the problem about the area. The area is given to you. We know that the area is 24 squared units. Remember what the equation to find height is. It's h = A/b. Substitute the variables for your numbers. h = 24/30.

24/30 = 0.8.

This means that your height is 0.8. This would be 8/10 in fraction form, but you can simplify it further to 4/5.

Hope it helps. Good luck!

Find the distance between points M and N. and if anyone could kinda explain how they got it so i can do the next ones on my own

WINSTONCH [101]

Answer:

$\sqrt{13} = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${3}^{2} + {2}^{2} = {c}^{2}$

$9 + 4 = {c}^{2}$

$13 = {c}^{2}$

$\sqrt{13} = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

We can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

N[−3, 2] M[−6, 0]

$\sqrt{[3 - 6]^{2} + [0 + 2]^{2}} = D$

$\sqrt{[-3]^{2} + 2^{2}} = D$

$\sqrt{9 + 4} = D$

$\sqrt{13} = D$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.

If m 2X = 34º and m ZZ = 26, what is mZY? OmZY = 26 OmZY = 34 mZY = 60°

Gre4nikov [31]

Answer:

The measure of the angle Y in given triangle is 120 º.

Step-by-step explanation:

Here, in ΔXYZ

∠X = 34 º , ∠Z = 26 º

By, ANGLE SUM PROPERTY of a Triangle:

Sum of all the interior angles in any given triangle is always 180 º.

⇒ ∠X+ ∠Y + ∠Z = 180 º

or, 34 º + ∠Y + 26 º = 180 º

or, ∠Y = 180 º - 60 º

⇒ ∠Y = 120 º

Hence, the measure of the angle Y in given triangle is 120 º.

What is the correct first step to solve this system of equations by elimination?

storchak [24]

$\bold{\huge{\pink{\underline{ Solution }}}}$

$\bold{\underline{ Given }}$

We have given two linear equations that is 2x - 3y = -6 and x + 3y = 12 .

$\bold{\underline{ To \: Find }}$

We have to find the value of x and y by elimination method.

$\bold{\underline{ Let's \: Begin }}$

$\sf{ 2x - 3y = -6 ...eq(1)}$

$\sf{ x + 3y = 12 ...eq(2)}$

Multiply eq( 2 ) by 2 :-

$\sf{ 2( x + 3y = 12 )}$

$\sf{ 2x + 6y = 24 }$

Subtract eq(1) from eq(2) :-

$\sf{ 2x + 6y -( 2x - 3y) = 24 -(-6)}$

$\sf{ 2x + 6y - 2x + 3y = 24 + 6 }$

$\sf{ 9y = 30 }$

$\sf{ y = 30/9}$

$\sf{\red{ y = 10/3}}$

Now, Subsitute the value of y in eq( 1 ):-

$\sf{ 2x - 3(10/3) = -6 }$

$\sf{ 2x - 10 = -6 }$

$\sf{ 2x = -6 + 10}$

$\sf{ x = 4/2}$

$\sf{\red{ x = 2}}$

Hence, The value of x and y is 2 and 10/3
